I am using Ruby MRI 2.0.0 and Rails 3.2.12 on a Ubuntu 12.04 TLS VPS and attempting to setup email notifications in my app. It was working fine a few days ago, but not anymore. My web host is OVH.
My SMTP settings:
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => '[email protected]',
:password => 'secret',
:authentication => 'plain',
:enable_starttls_auto => true
}
Using RAILS_ENV=production rails console
:
class MyMailer < ActionMailer::Base
def test_email
sender = "[email protected]"
receiver = "[email protected]"
mail from: sender, to: receiver, subject: "Hello!", body: "World!!"
end
end
=> nil
MyMailer.test_email.deliver
The output:
Net::OpenTimeout: execution expired

I tried the following:
exception_notification
gem was added to the setup a few days ago. I tried to comment its line in Gemfile
as well as its matching configuration, and run bundle install
. After restarting the server, the issue is still present, even if I delete and recreate the gemset.Does someone have a possible clue as to how to resolve this issue?
Thanks!
First, do a direct connection with Telnet:
telnet smtp-relay.sendinblue.com 587
Trying 94.143.17.4...
This is the basic connection troubleshooting, and works with any provider or port. Replace SendBlue and the 587 port with your actual hostname/port.
If you get this error:
telnet: Unable to connect to remote host: Connection timed out
then, the problem isn't in Rails.
In the above example, the problem is in the port number. Services like sendinblue or mandrill (I believe gmail too) don't support the 587 port anymore. "2525" is the new "587".
If you get a timeout on telnet, check this:
